Maxim Integrated MAX6334UR16D3 Microprocessor Reset Circuit

The MAX6334UR16D3 from Maxim Integrated is a highly reliable microprocessor (µP) supervisory circuit designed to maintain system integrity during power failures or unexpected events. This precision device is engineered to monitor the power supply voltage of digital systems and provide a reset signal to the host processor when necessary, ensuring proper operation and startup.

With a factory-trimmed reset threshold voltage of 1.6V, the MAX6334UR16D3 is suitable for low voltage applications, including those operating on 1.8V power supplies. The device features a built-in manual reset input, allowing for a system reset to be initiated by external hardware or software control, providing additional flexibility and control to the system designer.

One of the key features of the MAX6334UR16D3 is its minimal component count, which allows for a compact and cost-effective design. The device is available in a tiny SOT23-3 package, making it ideal for space-constrained applications where board real estate is at a premium.

The MAX6334UR16D3 also boasts a low supply current of only 5µA (typical), which contributes to the overall power efficiency of the system it is embedded in. This characteristic is especially valuable in battery-powered devices where power conservation is crucial.

Additional features of this reset circuit include a reset timeout period of 140ms (min), which ensures that the µP has sufficient time to return to a known state before resuming operation. The device operates over a wide temperature range of -40°C to +85°C, making it suitable for use in diverse environments and applications.

Overall, the MAX6334UR16D3 is a robust and reliable solution for microprocessor system monitoring. Its precision voltage monitoring, low power consumption, and compact form factor make it an excellent choice for designers seeking to enhance the stability and reliability of their digital systems.
